A clogged dryer vent can be extremely dangerous
Lint is highly flammable and can pose a severe fire hazard when dryer vents are not cleaned regularly and properly. According to the U.S. Fire Administration’s National Fire Data Center, clothes dryers are responsible for more than 15,000 structure fires around the country each year, and 80 percent of those fires start with clogged dryer vents.
Another dangerous aspect of a clogged dryer vent is the possibility of the release of poisonous gas fumes. Blocked vents can cause carbon monoxide to back up into your home instead of being exhausted outdoors
